Lecture 5: The ideal operational amplifier

Ideal Op-Amp Properties g Property No.1: Infinite Open-Loop Gain n Open-Loop Gain Avol is the gain of the op-amp without positive or negative feedback n In the ideal op-amp Avol is infinite g Typical values range from 20,000 to 200,000 in real devices g Property No.2: Infinite Input Impedance n Input impedance is the ratio of input voltage to ... ................
